Analysis of Grip Strength and Its Explanatory Factors in Older Patients with Gastrointestinal Tumours.

ABSTRACT

Aim: To investigate the grip strength of older patients with gastrointestinal tumours and analyse its explanatory factors. Methods: A total of 170 older patients with gastrointestinal tumours admitted to the Gastrointestinal Surgery Department of a Grade-III hospital in the Zhejiang province from January 2022 to December 2022 were selected as the investigation participants. Among them, there were 102 cases of gastric cancer (60.0%) and 68 cases of colon cancer (40.0%). There were 110 male patients (64.7%) and 60 female patients (35.3%), with patient ages ranging between 64 and 82 years old. A cross-sectional survey was conducted using a general data questionnaire, grip apparatus and the Nutritional Risk Screening 2002 (NRS-2002) score. Multiple linear regression was used to analyse the explanatory factors on the grip strength of older patients with gastrointestinal tumours. Results: The grip strength of older patients with gastrointestinal tumours was 25.3±5.3 kg. Multiple linear regression analysis showed that gender, age, disease, body mass index (BMI), albumin concentration and the NRS-2002 score were the main explanatory factors on grip strength (P<0.05). Conclusion: Grip strength was lower in older patients with gastrointestinal tumours and was lower in females, those aged ≥70 years, patients with colorectal cancer, individuals with a BMI of <18.5, those with an albumin concentration of <35g/l and those with an NRS2002 score of ≥3. Clinical staff should dynamically evaluate the level of grip strength in patients with gastrointestinal tumors and develop individualized interventions based on the related explanatory factors.
